Taking the stress out of choosing the right stress test
...e problems such as wheezing, says Dr. Patel. In patients with those problems, physicians opt for dobutamine, the least used agent because it creates a catecholamine
surge that causes the heart to shake and blood pressure to rise and can be harmful in patients at high risk of a heart attack.

However, the greater surprise was yet to come, say the investigators. Deletion of a core clock gene completely abolished both the catecholamine

Targeting the Adrenal Gland Could Be Key Against Heart Failure
...red,” explains Dr. Koch, who also heads the George Zallie and Family Laboratory of Cardiovascular Gene Therapy in the Department of Medicine. “If less catecholamine
is presented to the heart, then the beta receptors restabilize and that improves heart function. The heart is allowed to relax and get better.”
Genetic Mechanism Helps Explain Chronic Pain Disorders
